2 Release Notes for Bacula 2.1.24
4 Bacula code: Total files = 516 Total lines = 244,807 (*.h *.c *.in)
6 This Director and Storage daemon must be upgraded at the same time,
7 but they should be compatible with all 2.0.x File daemons, unless you
8 use some of the new features that affect the FD. In other words, you should
9 not have to upgrade all your File daemons. However, bat works only with
10 a 2.1.8 Director or greater.
12 !!!!!!!!!!!!!!!!!!!!!!! Please Note !!!!!!!!!!!!!!!!!!!!!!!!!!!
13 Restore on Win32, and in particular on Vista is untested. Please
14 test before relying on it. It should backup and restore reparse
16 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
18 Changes since Beta release 2.1.22
19 - Different locking in reservations and despooling systems,
20 which means more micro-locking and less macro-locking, which
21 should give a lot more concurrency at the expense of slightly
22 (<0.1%) more overhead due to more locking/unlocking, but
23 concurrent jobs should run much faster.
24 - Patch from Sergey Svishchev <svs@ropnet.ru> that fixes bug in
25 migration code where a job that spanned two volumes was
28 Changes since Beta release 2.1.20
30 - Due to a typo, I had inadvertantly turned off batch insert mode.
32 - Possible fix for bug #888 (dropped comm lines using TLS).
33 - Test version of Win32 binaries for Vista.
35 Changes since Beta release 2.1.18
36 - Fixed bug #886 (multidrive autochanger: SD doesn't use drive with
37 loaded tape but uses first drive).
38 - Fixed bug #807 Restore encrypted backup failed on Windows 2003
39 This was indeed a Win32 issue.
41 Changes since Beta release 2.1.12
42 - Version 2.1.14 not released.
43 - Possible solution to Win32 encryption restore signature errors.
44 - Reload with syntax errors in @include now works.
45 - Gnome console builds with encryption.
46 - Fixed bugs #864, 872, 874, 882, 882, 877, 886, 885.
47 - License is now GPL v2 without modifications, fix a few copyright
48 mistakes made when adding FSFE copyright notice.
49 - Fix update all from pool to pass pool name.
50 - Correct reservation system bug that invalidated Volumes by
51 calling find_next_appendable volume before acquiring a device.
53 Changes since Beta release 2.1.10
54 - Lots of new bat functionality !!!!!!
55 - Additional drive reservation algorithm that should solve a lot of
56 the problems experienced with multiple drive autochangers.
57 - Reload was broken in 2.1.10 -- now fixed.
58 - Storage daemon status command enhanced to more clearly show Volume,
59 pool and media type when a job is waiting.
60 - Made bsmtp work with more strict SMTP servers.
61 - Detect doubly freed buffers in smartall.c
62 - Reduce the impact of a backup on the FD's memory usage (OS file
63 caching). This works only on POSIX compliant systems. This allows
64 users to work with less interference on a Client machine during a
66 - bat should now handle non-English characters.
67 - ./configure now permits --enable-batch-insert (as well as --disable...).
68 This feature is enabled by default if your SQL libraries are thread
70 - The default setting for SQLite3 is now 'PRAGMA synchronous=OFF'.
71 This makes it run 30 times faster, but increases the possiblity
72 of a corrupted database if your server shuts down unexpectedly.
73 The default behavior can be changed in src/version.h
75 Areas requiring caution or testing:
76 - You must have Qt4 Version 4.2 or greater loaded to build bat
77 - You must have the thread safe version of MySQL client libraries loaded
78 to build with MySQL enabled.
79 - The Volume management in the Storage daemon is extensively rewritten.
80 It appears to function much better, but is largely untested under
81 severe production stress conditions (multiple drive autochangers, ...).
82 - Volumes are pruned only when absolutely necessary -- this may cause
83 your database to grow compared to prior Bacula version.
84 - Socket level heartbeat is untested.
85 - Solaris door and even port files are no longer restored (equivalent
86 to what we do with sockets).
87 - Win32 servers are untested, and very likely not to work.
88 - SQLite is no longer supported for Solaris -- it fails too often with
91 The major new features are:
92 - Much faster insertion of attributes (somewhere around 10 times),
93 many thanks to Eric Bollengier and Marc Cousin.
94 - First cut of bat (Bacula Administration Tool). Note to build
95 bat you must explicitly enable it on the ./configure line, you
96 must have the Qt4 version 4.2 or later libraries loaded, and
97 qmake and the other Qt4 tools must be available. bat is ALPHA
98 software. A large part of the work was done by Dirk Bartley.
99 - Red/Black restore in memory tree (500 times faster loading).
100 - The Regex Where code to allow easier relocation of restored files
102 - Socket level heartbeat for all connections (untested).
103 - posix_fadvise() use in the FD to improve performance.
104 - Simpler locking in the SD in the reservation system.
105 - Much improved Volume reservation code that should eliminate most
106 conflicts experienced in multiple drive autochangers.
107 - Detection of file size/date change during backup if enabled.
108 - New Recycle Pool feature -- thanks to Eric.
109 - Efficient implementation of very large include/exclude lists.
110 - Volumes are no longer pruned during 'status dir'
111 - Pruning is now more efficient, and if a Volume is purged,
112 during pruning, it is immediately discovered.
114 Other features or bug fixes:
115 - Fixed bugs: 856, 854, 845, 847, 846, 809, 772,
116 822, 825, 824, 808, 802, 797, 798, 795, 789, 791,
117 788, 780, 763, 782, 612, 767, 775, 621, 772, 764,
118 766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
119 - Only the minumum number of volumes are pruned rather than
120 all volumes in the pool.
121 - wx-console renamed to bwx-console
122 - gnome-console renamed to bgnome-console
123 - Migration preserves original job's FileSetId
124 - Spooling implemented for migration jobs.
125 - Config files can be read through a pipe, by specifying a leading |
126 in front of the configuration path/filename.
127 - New memory command (bconsole) that will print the current Director's
128 memory usage, and a in use buffer dump.
129 - Solaris door and event port files are no longer restored.
130 - Console name changed from *Console* to -Console- to accomodate Win32
131 filename restrictions.
132 - Corrected Win32 ftruncate bug.
133 - Additional version information added to Job reports.
134 - New -8 option for bsmtp to specify UTF-8 encoding type.
135 - bsmtp will no longer add < > to target (from, to, cc) if there
136 is already a < in the target.
137 - Perfer Mounted Volumes extended to mean a volume that is being
138 mounted by another job.
139 - Runscript timing set to same as version 1.38.11
140 - New TLS Allowed CN directive(s) permitted.
141 - New bconsole 'exec' command to run external script/command.
142 - Turn on FreeBSD/OpenBSD code to set EOT model on tape.
143 - Drop from root done before database is opened.
144 - database user and name can be configured with:
145 --with-db-name=name --with-db-user=user
146 - turn on wait_for_drive in mtx-changer script.
147 - rework how bar codes are handled in mtx-changer script.
148 This appears to have been an unreported bug.
149 - Updated nagios plugin supplied by Christian Masopust
150 - Better restricted console ACL checking.
151 - New Client Connect Wait directive in Storage daemon so that
152 users can configure how long SD waits for FD connection.
153 - Bacula will no longer permit pruning of the currently running
154 job (note, if other jobs are running, they may be pruned).
155 - Sockets are no longer restored.
156 - dbcheck works in 300K chunks so will typically run faster.
157 - Include/Exclude lists can now be efficiently handled for quite
158 large sizes -- tens of thousands of entries.
159 - Several memory leaks in migration and database usage were fixed.
160 - New console keyword restoreclient, which specifies the client to
161 which the restore will be sent. The client keyword specifies
162 the backup client. The restoreclient keyword is optional if it is
163 not specified, the backup client will also be the restore client.
164 - The disk file size is now checked to ensure that it agrees with the
165 catalog value before Bacula will append to the disk (same as tape
